I recently bought the Goliath and used it for the first time this weekend and I loved it, only I have a couple of questions for you climbing guru's... I noticed that the black plastic wascomingoff of the cables where they lock into the stand. Could that be normal wear due to the fact that it's rubber on metal? and last, should there be a strap or something that attatches the top to the bottom of the climber while climbing to prevent to lower part of the climber from sliding down under you accidentally while getting into position?
